Clearing skies, cooler, low 40

A cold front crossed the region early this morning, with clearing skies and a cooler airmass continuing to settle in behind the front tonight. Overnight lows to drop to about 40 degrees.

Sunny skies are expected all day long tomorrow for the first full day of fall. Temperatures will be on the cool side once again. Today's highs only reached the upper-60s, and we're expecting tomorrow's numbers to end up in the mid-60s. Winds will be out of the northwest again at 10 to 20 mph.

This workweek looks very similar to last week. Sunshine will dominate all the way through next weekend as a huge area of high pressure remains parked over the eastern U.S. Temperatures also feel comfortable for late-September with highs near 70 degrees this week (except Monday's high of 64) and nights a few degree cooler than normal.

The autumn equinox occurs precisely at 4:44 p.m. this afternoon. For a look at some weather dates to keep in mind this fall season, visit the CBS3 Pinpoint Weather Blog.
